Morphological study of the jejunal and ileal Peyer's patches of three-month old calves

The current study was conducted with the aim to described the light and electron microscopic features of jejunal and ileal Peyer`s patches of three-month old calves. The samples of jejunum and ileum portion of small intestine of three-month old calves were taken and processed for light microscopic,...

The samples of jejunum and ileum portion of small intestine of three-month old calves were taken and processed for light microscopic, scanning electron microscopy and transmission electron microscopy examinations.

The Follicle Associated Epithelium (FAE) is composed of absorptive epithelial cells or enterocytes and intraepithelial lymphocytes but lack of goblet cells and specialized cells or membranous cells (M cell). The jejunal Peyer`s patches consist more intraepithelial lymphocytes than that of the ileal peyer`s patches. The number of intraepithelial lymphocyte was significantly higher (p<0.05) in villi than those of crypts.
